CI: fix test 'with remote-node identity disabled'
CI: fix test 'with remote-node identity disabled'

This test code being removed has no effect on the CI currently, so it
either doesn't run in regular test environments or is otherwise not
effective in evaluating whether the remote-node identity option is
performing correctly, so the extra test code is unnecessary.

Fixes: #15491
